VENTlL'ATlNG APPARATUS FOR RAlLWAY-CARS.

QPECIFICATION forming part of Letters Patent No. 373,898, dated November 29, 1887.

Serial No. 204,658. (No model.)

To all whom it may concern.-

Be it known that I, GUSTAVE LEVE, of the city of New York, in the county and State of New York,'United States of America, have invented certain new and useful Improvements in Ventilating Apparatus for Railway-Cars; and I do hereby declare that the following is a full, clear, and exact description of the same.

The invention relates to that class of carventilators which provide for the drawing of air from the exterior into the car, purifying same, and then distributing it through registers to different parts; and my improvements have for theirobject to simplify and cheapen the construction and arrangement of the ventilator, and to improve its operation without necessitating the provision of a large separate compartment to contain the apparatus. In other car-ventilators, arranged according to the system first. mentioned, ioeboxes or refrigerators and water-pans have been made an essential, while by my invention no such medium is needed, and very little alteration is required to adapt my invention to cars of'all classes now in use; and in every case the apparatus is the same, whether used in winter to supply pure warm air to the car or in summer to replace the vitiated air with afresh purified supply from the outside. 7

My invention consists in combining, in a railway-car having an isolated heater, a filtering-chamber above the heater having an airinlet opening directly into it, a heating-chamber surrounding the smoke-pipe of the heater and communicating with the filtering-chainber, and a vertical flue which conveys the air to horizontal flues extending within the car, and having registers opening into the interior.

For full comprehension of my invention reference must be had to the accompanying drawing, forming part of this specification, in which similarlettersof reference indicatelike parts.

The said drawing is a longitudinal sectional elevation of part of a car, clearly illustrating the improvements.

A indicates the main body of the car, B the ordinary heater-chamber, and B the par- 0 represents the stove or heater, of any usual type, having a smoke pipe or flue, G, extending up through the roof of the car, -D showing part of the water-tank, and d d the hotwater pipes connecting the tank and heater and passing through the flue E around the sides of the car in the ordinary manner, 6 showing one of the registers or grated openings in said box.

F represents any suitable hood or funnel, located, by preference, on the car-roof, (although it may be at the side or end, if found desirable,) and either made with double flaring-mouths,'as shown, or adapted to turn on aswivel, so as to adapt itself to whichever direction the car may be moving in, andf is a pipe leading from said hood to the interior of a box or chamber, G, formed in or partitioned. off from the heater-chamber'B. About midway in this box or chamber G, I place a shallow platform or box, H, having a grated or perforated bottom, It, upon which I place dampened sponges K or other suitable airfiltering medium.

L is a hinged damper, (orslide,ifpreferred,)

arranged to be adjusted by a handle projecting through the side of the box, or in any other suitable way,said damper being, by preference, located near the bottom of the box G, to correspond With an opening, 9, in the wall G, dividing it from another chamber, M, formed around the smoke-pipe O'or upper part of the heater. This chamber M has connected to it a pipe or conduit, N, leading down to and forming a close junction with the box G containing the heating-pipes cl d Atthe points where these pipes pass into the conduit N close joints must be formed.

The box or chamber G will have a suitable door, (not shown in the drawing) and the conduit N may also have a damper, n, as shown in dotted lines, if found desirable.

Although in the drawing I have shown the different chambers formed with metaI-sheeted boards, it will be understood that the whole apparatus may be constructed of sheet metal of suitable weight, and the different joints formed by soldering or riveting, the shape and precise arrangement of the chambers and conduit within the heatercompartment being also immaterial.

The external air forcibly enters the hood F as the car is traveling and passes through the pipe f into the box or chamber G, being cleansed and purified from dust, cinders, gases, &c., by its filtration through the sponges or other medium upon the grating, passing thence (the damper L being opened) into the chamber M, and, it there is a fire in the heater 0, will be warmed by the heat radiated from the smokepipe C before entering the conduit N, from which it passes to the flue E, and, by means of the different gratings or registers o, is disseminated throughout the car.

The vitiated air in the car passes off, as usual, through ventilators O, placed in the upper part of the side walls.

What I claim, and desire to secure by Letters Patent, is as follows;

In combination with a railway carhavinga heater inelosed in an isolated chamber, and fines E for containing heating-pipes, an airinlet pipe, an air-filtering chamber, G, com- 20 municating directly therewith, a heatingehamber, M, surrounding the smoke-pipe of the heater and communicating with the filtering-chamber, and a vertical flue connecting the heating-chamber with the flucs E, the fil- 25 tering-charnber and the heating-chamber being entirely separated from the chamber which contains the heater, substantially as described.
